Comparison of anti-inflammatory effect of atorvastatin with rosuvastatin in patients of acute coronary syndrome

摘要

Objectives:To compare anti-inflammatory effect of atorvastatin and rosuvastatin in patients of acute coronary syndrome.Materials and Methods:The study was a prospective, open-labeled, randomized and single-center study conducted on 100 patients of acute coronary syndrome. Patients were assigned to atorvastatin 40 mg daily or rosuvastatin 20 mg daily for 4 weeks. C-reactive protein (CRP) levels, lipid profiles, erythrocyte sedimentation rate (ESR) and adverse effects were measured at beginning and at the end of 4 weeks.Results:Baseline parameters and clinical profile did not differ between the two groups. CRP levels significantly decreased from beginning to the end of 4 weeks in both atorvastatin and rosuvastatin groups (from 35.48 to 23.07 mg/l and from 35.88 to 19.91 mg/l respectively, both P < 0.001). However, there was significant difference between the levels of CRP in patients of the rosuvastatin group as compared to the atorvastatin group (19.91 ± 6.32 vs 23.07 ± 7.47, P < 0.05). In addition, both the drugs were associated with a reduction in total cholesterol, LDL levels and ESR at the end of 4 weeks as compared to the beginning (P < 0.001 for all comparisons).Conclusion:Both atorvastatin (40 mg) and rosuvastatin (20 mg) are effective in decreasing CRP and LDL cholesterol levels even in a short duration of 4 weeks. Rosuvastatin was found to be more effective in decreasing CRP levels.
